To all 'w ham it may concern .1

Be it known that 1,; Anrrronsn IIQJKUR- snnnn'r, a citizen of the United StatesereQ slding 1n the city, county, and State of New 'York, have invented certain new and useful. nat-ed by correspondmg reference numerals. The basal of the machine carrles. a stand ":Improvements in Bead-Sewing Machines, of which the following is a specification.

My lnvent on relates to sewing machlnes whiehare adapted tor use inattachingbeads or slmllar ornamental elements to a fabric;

andmy improvements are directedparticularly to the means for feeding or propelling the beads one by one down to their proper positions. upon the fabric, after each head has been separated from those above t r the bead separating mechanism. e

l-Ieretofore, in the art, heads have been.

To the loweimend strung loosely upon a thread, which thread 1 has been secured to thetabrie bysuitable stitching meeh anism, the beads sliding down along thethread, under theinfluenceof.

gravity until theyreaeh a se'parator, which passes them one by one and allows them toslide on down the thread to the point where they are to be fastened to the fabric. 1 This movement of the beads below the separator is dependent upon the weight otweach bead bemg sufficient to cause ltlto shde down the fl threadw irregularities of size in the thread, ao orloose fibres prqectlng firomit, or other elements. connected with the thread maytend to arrest thedesc'ent of ahead, or, if the M perforation through thebead is of an abnoryinal form, the bead maynot slide down the thread with the precision and certainty whieh are essentialt'or accurate work.

ltis the, object of myinvention to provide means for positively pushing or propelling the head. down the thread, below the separa 4U tor, to the fabric, so that it willassuredly reach its proper positionpromptly and ac eurately, as I will now proceed to pointout and explain, referring,- accompanying;- drawingsin which Figgl is,

of the bead separating mechanism and of the part of my auxiliary feed mechanism as .sociated therewith, the latter being partly 1n held to dutyby the guide arm insodoing, to the j 1e21 seam no. M7357.

section; and Fig. 4 is cross sectional view of the same, taken on the line etl o'l: lhg. 3,

looking down,- the bead guide and follower however being in their initial positions.

In all the figuresithe same parts are desigr injthe headoflthe machine, so that asthe .nut. 7 1S ralsed and lowered the tube Wlll be, turned first in one direction and thenin the.

other.

of the tube S are attached the bead guide .9 and bead follower suitable bearings inthe standard and arm is .10, which travel forward and back with the;

tube 8 as it is moved. first inone direction and then in the other, the follower being);

the head of the machine, e a

The bead separator 12 is also carried by the headoi the machine; and, in operation, the bead guide 9 and follower 10 move around it, forward and back, with each for ward movement causing one head to pass be.

11 carried low the edge 13 of the separator, from which fabric i U I Through suitable gears 14:, 15, shaft 16,

point it may slide down the thread to the gears 17, 18and shaft 19, the needle slide 20 is raised and lowered in the usual manner p erform its M st tch to cause the needle to makingmovements. Theseelements of the machine are shown as illustrating a type oiinechanisni, known in the art, with which my imprrwements may be combined, and not as embracing novel matter invented by me. y

In the faceofthe gear'IB l secure a wrist pin 21, on which is pivoted a piston rod 22, carrying a piston head 23, provided with suitable flap valve 24 andsliding in the cylinder 25,which is secured by suitable means,

as 26, to the standard 2.

A ball valve 27 controls the outlets from the piston cylinder, and from it a tube 28 is carried over to the head of the machine, and down to an annular terminal 29, positioned around andslightly above the separator 12.

This terminal is provided with a series of openings 30, 30, directed inwardly and downwardly toward a point below the bead separator; the arrangement being such that when air is forced into the tube 28, by the action of the piston 23, it will escape through the openings 30, 30, ininwardly and downwardly converging jets so as to drive down before it any loose or partially free article, such as a bead strung upon the bead thread, which will be urged down by the air jets until it reaches the fabric where the thread is attached to it.

As the air pump is adjusted, as shown, to make one upward stroke with each stitch movement of'the machine, it follows thatv "the separator, the head, in the type of maof the compressed air will e chine which I have illustrated, being free to drop after the-bead guide and follower have made about one quarter of their forward movement, at which pointthe force substantial and will continue to increase as the separating elements move forward. The down stroke of the piston 23 is preferably adjusted to correspond with the return movement of the separating elements.

For clearness I have omitted the fabric feeding mechanism and the means for changing the direction of feed.

But, as those skilled in the art understand,

' when the direction of feed is changed, the

position ofthe bead separator must also be correspondingly changed by moving the separator around the needle point, the feeder and follower elements being also moved so as to retain their normal positions relative to the separator Consequently if the air tube terminal is stationary, as I have illustrated it as being, it is desirable to have it providedwith a plurality of air jet ori- "fices, so that in whatever position the separator may be set there will always be jet openings pointing downward past the posi- I tion of the separator beneath which the beads descend.

I wish it to be understoodthat the means I have illustrated for carrying out my invention are to be considered as typical means and not asshowing the sole means for securing the ends in view. For mechanical equivalents or the like may be employed to give the same result, without de 'aarting from the spirit of my invention as claimed. For instance a continuous instead of an'intermittent current of air may be used if desired.

- Havin thus described my ini' e'ntion' what 1 greens? lf claim and desire to secure by lietters Patent of the United States is 1. The combination with the beadseparating mechanism of a bead sewing machine, of feeding means adapted to operate on the beads below their final point of separation.

2. The combination, with the bead-so arating mechanism of a bead sewing machine, of feeding means adapted to operate on the several beads successively below their final point of sepa-raton.

3. The combination, with a bead-separating mechanism of a bead sewing machine. of feeding means adapted to operate on the beads below their filial point of separation to propel them toward the fabric.

l. The combination, with a bead-separating mechanism of a bead sewing machine, of pneumatic feeding means adapted to operate on the beads below their final point of separation.

5. The combination, with a bead-separating mechanism of a bead sewing machine, of: pneumatic feeding means adapted to cause an'air current to operate on the beads below their point of separation.

6. The combination, with a bead-separab 'ing mechanism of a bead sewing machine,

of pneumatic feeding means adapted to cause a plurality of air currents to operate on the beads below their point of separation.

7. The combination, with means in a bead sewing machine embodying a bead separator, of means for producing a current of air, means for conducting it to a point near the bead separator, and means for discharging it downwardly past the separator.

8. The comliiination, with means in a bead sewing machine embodying a bead separator, of means for producing a current of air, means for conducting it to a point near the bead separator, and means for discharging it inconverging jets downwardly past the separator.

9. The combination, with means in a bead sewing machine embodying a bead separator, of means for producing a current of air, means for conducting it to a point near the bead separator, and means for discharging it in converging jets past the separator toward a selected boa d position.

10. The combination, with the bead-sou arating mechanism of a bead sewing machine, of feeding means adapted to operate intermittently on the beads below their point of final separation.
